123NQ100-1

Application Field and Working Principle

Introduction

The 123NQ100-1 series of diodes are single rectifiers that helps control the flow of current in an electrical circuit. It is an important component of most modern electronics, as it allows electrical currents to flow in one direction while blocking current in the opposite direction. This diode has a power dissipation of 1.0W and a standard peak reverse voltage of 100V.

Applications

The 123NQ100-1 series of diodes are widely used in a variety of electronic components, such as protection diodes, converters, switching power supplies, DC-DC converters, rectifiers and other control circuits. It is also used in automotive electronics systems, such as airbag system and other safety systems. The diode is also often used in three-phase motor drives.

Working Principle

The 123NQ100-1 series of single rectifiers are based on the principle of PN junction diode. The diode is made up of two semiconductor layers, the ‘P-type’ layer and the ‘N-type’ layer. When a voltage is applied to the diode, it structures a so-called depletion region, which prevents the passing of current in the reverse direction. This is known as ‘reverse bias’. On the other hand, when the voltage is applied in the forward direction, it forms a thin bridge of electrons between the two layers, allowing current to flow freely in the forward direction. This is known as ‘forward bias’.

Conclusion

The 123NQ100-1 series of single rectifiers is an important component of many electronic and automotive systems today. In addition to controlling the direction of current, it also provides protection against short-circuiting and overloading, making it an invaluable tool for both engineers and technicians.
